Hi,
Whilst working on the Reproducible Builds effort [0] we noticed that
perl could not be built reproducibly.
This is because it ships a number of build-related header files that
include the build path in various guises. Assuming these files are
actually useful in the binary package, a patch is attached that
sanitises these in debian/rules prior to the final creation of the .deb.
To be clear, Perl is not entirely reproducible with this change — I
need to address the variations added between a /usr-merged system and
one that is not. That part should be incoming soon.
